Trinna B.
I had a feeling that my husband was cheating on me. I hired Graham Meserve to find out the truth. They started right away and provided the proof I needed to see with my own eyes. Through the process they were very supportive of my emotions.

Very impressed with Patrick Ong and his team. They have assisted us with several insurance claims and have saved us thousands of dollars. I would recommend them to anyone that is in need of a qualified professional investigator.
